1. To judge the bed condition with the probe rod. Jigger bed under the water surface, can not directly see the material layering conditions, the operator must be probed with the help of a probe rod to check the looseness of the bed, in order to judge whether the wind and water system is reasonable, and whether the bed distribution is appropriate.

2. Use wind and water correctly. At present, the general understanding of jigging machine operation is that the wind and water volume from the feed port to the discharge port are reduced room by room, the reason is that the weight of jigging bed from the feed port to the discharge port is reduced room by room, and it is believed that the jigging bed in the movement process from the feed end to the discharge end, the discharging of materials by the permeable sieve of the various chambers along the discharge and the discharging of the discharge mechanism has been discharging the high ash materials, so that the bed layer is reduced room by room.

3、Control feeding. The fluctuation of the coal quality of jigger and the change of feeding quantity have a direct influence on the sorting effect of jigger.

4、Correctly understand the relationship between the exhaust period and the penetrating screen.The jigging cycle curve produced by the normal operation of LTA1010/2 jigger is sinusoidal, with the characteristics of the rising water flow uniformity.This series of jigger has the advantages of beneficiation such as large handling capacity, high recovery rate and continuous work.
